To all whom it may concern.-

Be it known that I, SLVESTER OSEPH lVIoomc, of the city of London, in the county of Middlesex, Province of Ontario, Dominion of Canada, a subject of the King of Great Brita-in, have invented certain new and useful Improvements in Gas-Meters, of

which the following is a specification.

This invention relates to improvements in the ordinary type of dry gas meter in which the gas chambers -01" bellows are formed with movable diaphragms, which actuate the flag wires which move, througl'i'suitable connections, the valves and registering mechanism, and my object is to devise means for increasing the capacity of the-meter without materially increasing the dimensions of the-' meter or increasing the rate of operation of the mechanism operating the valves and registering mechanism.

I attain my object by providing for a greater range of movement than usual for the diaphragms and by connectingsaid diaphragms with the flag wires by compound lever systems which permit of the greater movement of the diaphragms without increasing the angular movement of the flag wires.

The invention is hereinafter more specifically' described and illustrated in the accompanying drawings in which Figure 1 is a plan view, partly broken away, of parts of a meter constructed in accordance with my invention;

Fig. 2 a front elevation, partly broken away, showin the same parts;

Fig. 3 a front elevation illustrating a modification of the compound lever through the medium of which one of the diaphragms actuates the flag wire; and

Fig. 4 a plan view, partly in section of the compound lever system shown in Fig. 3,

In the drawings like numerals of reference indicate corresponding parts in the different figures.

The gas meter is of ordinary type in every respect save for the connections between the fiag wires and the diaphragms, and only such portions of the meter are herein described and illustrated in the drawings as are necessary to a proper understanding of the mode of operation of the improved construction.

1 are the flag wires to which are connected the rockarms 2 which, by means of links shaft -5.

3, 'are'connected to the crank *1 of the crank From this cran k shaft the valves :and registering device are :operated in the usual manner. The'va'l-ves and registering device,-'not forming part :of the present in-- ventio'n, are omitted to permit of the better showing of'ithe parts more directly :associated with the improved constructions.

'iDhe diapl1ragms6,'as usual, form the ends of bellows of which 7 are the *usual annular leather :sides. These c lia'phragms are vprovided with the'us'ual guiding rock arms 8 secured "to the roc'k shaft 9 journaled in suitable hearings on the b0ttom of the casing of the meter. To each flag wire is connected lever arm" 0, which extenc'ls we'll 'past the center of the diaphragm. and can therefore be made considerably longer than the ordinary lever arm which extends from the flag wire to the center of the diaphragm.

A second lever arm 11 is fulcrumed on the casing, preferably by being secured to a rock shaft 12 journaled in bearings secured to the end of the casing opposite the flag wire. The lever arm 11, in the preferred construct-ion shown in. Figs. 1 and 2, thus rocks on an axis substantially parallel to the axis of flag wire lever arm 10. The flag wire lever arm 10 has a sliding and rocking connection with the lever arm 11 between the ends of the latter.

The preferable arrangement is shown in Figs. 1 and 2 in which amember 13 has its ends pivoted in brackets 14: secured to the lever arm 11, which ispreferably double as shown. In the member 13 is formed a hole through which the flag wire lever arm 10 is adapted to slide. The lever arm 11 thus maintains its operating connection with the flag wire lever arm 10 notwithstanding the constant changes in the relative position of the two lever arms as the diaphragm travels in and out.

While the construction shown in Figs. 1 and'2 is preferred, other arrangements are possible For instance, in Fig. 3 the second lever arm 11 is shown extending at right angles to the'flag wire lever arm 10, which latter is shown as extending through a slot formed lengthwise of the lever arm 11.

By adopting a compound lever system as illustrated as the operating connection between each diaphragm and its corresponding flag wire, the length of travelof each diaphragm may be materially increased Without rocking the flag wire lever arm through a substantially greater are than is noW commonly'the case; Consequently there is no greater movement of the flag Wireand the parts actuated thereby. A meter of greater capacity is thus obtained Without any greater .Wear and tearon the valves or parts actuating the registering mechanism. Outside the special constructions described, the only changes required in the meter will be to construct the annular leather sides 7 so as to provide for the greater movement of the diaphragms and to suitably calibrate the registering mechanism.

I 'What I claim as my invention is 1. In a meter provided ,With movable diaphragms operating flag Wires, Which by suitable rock arm and linkage systems actuate the valvesand registering mechanism, f 3 a compound lever system between each flag Wire and its corresponding diaphragm comprising lever arm connected to the flag Wire; a lever arm pivotally connected to the diaphragm; and a stationary part on which the lever arm is fulcruined, said lever arms having a rocking and sliding engage: merit the one With the other.

2 A specific construction of the device setforth in claim 1 in Which the second lever arm is arranged to rock .on an axis parallel to the axis of the flag Wire lever arm and is fulcrumed at the opposite end of the meter and the connection between the tWo lever arms comprises a member pivotally connected to one lever arm and through which the other arm slides. a

3. A specific construction of the lever system set forth in claims 1 and 2 in which the second lever arm is double and thecon'ne'cting member through which the flag Wire lever arm slides is pivoted to each part of the arm. Y
